 Abstract

Inhibition properties of 2-Acyl pyridine derivative on mild steel in 1 M HCl was investigated using Field Emission Scanning Electron Microscope (FE-SEM) and Atomic Force Microscope (AFM). FE-SEM images of mild steel surface in the presence of inhibitors remains smooth with very less no. of pits as compared to blank acid solution. In the presence of inhibitors, AFM studied show that the variation in height sensor and the average surface roughness values obtained, are very less as compared to that obtained in blank solution. FE-SEM and AFM results showed that both the inhibitors 2-APN and ACN possess very good inhibition ability but 2-APN show comparatively better inhibition property than ACN. Both the results obtained from FE-SEM and AFM studied are in good agreement.

 Abstract

Cast aluminium alloys have attracted significant consideration in the automotive and aerospace industries due to their lightweight nature, cast ability, and one-of-a-kind mechanical properties. The demand and utilisation of cast aluminium alloys to improve the performance of products and reduce costs has been steadily increasing in recent years. There is a huge variety of aluminium alloys available, but the fact that they can be easily fabricated and have exceptional mechanical qualities makes them particularly appealing for a wide range of applications in the aerospace and automotive industries. Sand casting, gravity die casting, and pressure die casting are the typical methods that are utilised in the manufacturing process of cast items. These procedures were more prone to casting flaws than those of wrought goods because, at the present time, existing casting exercise is unable to consistently avoid casting errors. Consequently, casting defects were more likely to occur during these processes. However, in recent years, developments in casting methods have brought about significant improvements, which ought to be taken into consideration. Squeeze casting is one example of such an innovation.

 Abstract

Planning Commission or Yojana Aayog the prestigious policy making institution for a long period of 65 years, was dissolved on 17th August 2014. After India achieved independence, the formal model of soviet- style planning was adopted and accordingly planning commission was established on March 15, 1950 with the Prime Minister as its Chairman. In 1951 the first five-year plans was launched despite the economic liberalization initiated by Prime Minister P.V. Narasimha Rao in 1991, the Planning Commission continued but since 1997. It was felt that planning should be indicative in nature. However in view of the spirit and changed dynamics of New India's approach of less government and a move away from centralized planning. NITI Aayog with a new structure and focus on Policy, replaced Planning Commission on 1st January, 2015. Finance Minister Arun Jaitly outlined the necessity for creating NITI Aayog as "the 65years Planning Commission had become a redundant organization. It was relevant in a command economy structure, but not any longer. India is a diversified country and its states are in various phases of economic development along with their own strength and weakness. In this context a one size a 'one size fits all' approach to economic planning is obsolete. It cannot make India competitive in today's Global Economy."

 Abstract

One of the great advantages of promoting a company is that the necessary capital for business can be raised from the general public by means of the public issue. This advantage is, however, enjoyed only by a public company which is listed at a recognized stock exchange. After the receipt of certificate of incorporation, if the promoters of a public limited company wishes to issue shares to the public, he will issue a document called prospectus. Prospectus is a document which helps the public company to raising funds. It is an invitation to the public to subscribe to the share capital of the public company. The prospectus should be prepared according to the law and issuing procedure also takes place according to the law. In this paper we will try to know about the kinds and contents of included under the prospectus as per the Companies Act, 2013.

 Abstract

In the present paper, we would like to discuss about Newton-Raphson Method. This method is a powerful technique for finding the roots of given equations numerically. It is based on the simple idea of linear approximation using direct iteration method. Here, we have studied the roots polynomial equations using Programming of FORTRAN & MATLAB and compared their results. We found that this method is faster than Bisectional method as well as False position method.

 Abstract

Positron life time measurement have been done for CdSe. Samples were prepared in pellet form. Two identical scintillation detectors with the time resolution 300 ps have been used to measure start and stop signal. PAL spectra have been recorded by connecting electronics and MCA data acquisition system. PAL spectra have been analyzed by PATFITT88 software to fit the life times. Samples were annealed and measured life times. The variation in positron lifetime as well as intensity for CdSe due to heat treatment is observed. The value of life time (?1) is attributed to diffused vacancies at grain boundaries and second life time(?2) is attributed to annihilation of positron directly trapped in vacancy like defect in the samples. It is clear from the tables that there is small change in life-time (?2 ) of annealed samples in comparison to pristine life-time (?1) in CdSe. Secondary lifetime (?2) increases but corresponding intensity decreases respectively, which indicate that concentration of defects is decreased due to annealing
